The Physics of Music Essay examples - 880 Words

Physical science is the study of non-living matter which I will be talking about the physics of music, and how pitch and frequency play a role together in science. Physics is known to be the most fundamental science, based on the principle and concepts. It deals with matter, motion, force, and energy, (Shipman-Wilson Higgins, 2013). In this report I will be dealing with pitch, frequency sound and waves which are also dealing with physical science and how they our related. Sound is (a) the physical transmission of a disorder (energy) in a standard and the physiological response generally to pressure waves in air. However, the sound spectrum has much lower frequencies and is much simpler, with only three frequency regions; the infrasonic†¦show more content†¦Intensity is the average flow of energy per unit time through a given area of the medium and is related to loudness, (Shipman-Wilson-Higgins, 2013). Frequency is the number of waves that pass a fixed point per unit time; also, the number of cycles or vibrations undergone in unit time by a body in periodic motion. Frequency f is the reciprocal of the time T taken to complete one cycle (the period), or 1/T. The frequency with which earth rotates is once per 24 hours, (Merriam-Webster). Frequency is usually expressed in units called hertz (Hz). One hertz is equal to one cycle per second; one kilohertz (kHz) is 1,000 Hz, and one megahertz (MHz) is 1,000,000 Hz. The musical pitch an above middle C (the A string of a violin) has been widely standardized as 440 Hz, (Merriam-Webster). The frequency of a sound wave may be physical measured, whereas pitch is the perceived highness or lowness of a sound. A higher pitch has a higher number of vibrations. In Western music, standard pitches have long been used to facilitate tuning. A confusing variety of pitches prevailed until the 19th century, when the continual rise in pitch made some international agreement a matter of practical necessity, (Merriam-Webster). For example, a soprano has a high- pitched voice compared with a baritone. Pitch is related to frequency. If a sound with a single frequency is heard at two intensity levels, then nearly all listeners will agree that the more intense sound has a lower pitch.Show MoreRelated Physics of Music Essay851 Words   |  4 Pageschemistry either Georg Christoph Lichtenberg (1742-1799) Music is not purely a form of art. There is a great deal of science that goes behind the production of beautiful musical sounds. In order to understand how music is possible, one must have an understanding of physics. Physics allows us to create musical instruments with different tone qualities and the ability to be played in a certain way to produce a specific pitch or note.

You can imitate a compression wave by stretching out a slinky (you do have a slinky, dont you?) and flicking your finger against a coil at the end. Sound waves are not like the waves on the ocean or the waves you get by waving a stretched-out rope. Take a tuning fork (you do have a tuning fork

Chimpanzees are the closest living genetic animal to humans, even closer linked than gorillas. Scientist Joe Aguirre’s data conveys there’s a 1.2% difference between humans and chimpanzees DNA. Chimpanzees watch over their families and have long lasting friendships. They spend all day with their family playing, exploring the rainforest, grooming each other.According to one of PETA’s co-founders Alex Pacheco , there’s a different description of how chimpanzees spend their days in Silver Spring , Maryland. Pacheco went undercover at the Institute for Behavioral Research where Edward Taub, a psychologist with no medical training, experimented on chimpanzees by performing vicious surgeries, electric shock, and food deprivation. In one†¦show more content†¦The law excludes other animals such as rats, mice, and birds bred for research—who together constitute an estimated 90-95% of animals in laboratories ( Animals in the Use of Research). In 2013, Europe progressed farther than the U.S, by completely banning animal testing on products (Cosmetics and Animal Testing). This exhibits that U.S is behind the times and needs to make new legislation for animal testing. Due to the lack of conversation about animal testing in the presidential race, there seems to be no future legislation to prevent cruelty towards these animals. Since the government will not help the animals. It is up to the people of America to protest businesses who use animal experimentation. Until, the companies use alternative ways such as vitro testing, human tissue toxicity experimentation, and micro-chip testing ,the world will not be a humane place to live. In order to terminate animal experimentation in drug and cosmetic laboratories, companies must begin research in alternative testing methods. One alternative method is vitro testing , which refers to techniques done in an artificial environment outside of the living organism or cell. Experiments done in a whole organism, such as a mouse, are called in vivo experiments. In the past couple years, researchers have been using in vitro to study Parkinson s patients. According to Doctor Douglas A. Melton, a cell biologist, and George Q. Daley, a

I was supposed to land on top, where I could then crow victory and give in to my urges as a reward. Instead I ended up on my back, Cadotte settled firmly between my thighs. I was winded; he wasn’t even sweating. We will write a custom essay sample on Night Creature: Blue Moon Chapter 21 or any similar topic only for you Order Now â€Å"Tell me that you love me.† I heard the laughter in his voice and I smiled, too. â€Å"Kiss my – â€Å" His mouth covered mine. My brain melted as my body ignited. It had been so long since I’d had sex, and I had never had sex that began like this. I was so excited I could barely keep myself from arching and coming right now. But I was tired of getting off with my clothes on. I wanted him, all the way, so I gave up fighting. He kissed me forever. In my experience, limited as it was, guys don’t waste much time on kissing, especially when they know they’re on the fast track to something more. But Cadotte seemed to like kissing. Hell, if I was that good at something, I guess I would have liked to do it all the time, too. He nibbled at my lips, tasted me with his tongue, framed my face with his long, sexy fingers, stroking my chin with his thumbs, caressing my cheeks with his palms. And he didn’t stop with my mouth, giving equal and arousing attention to my neck, my eyelids, my ears. I never realized that the insertion of a clever tongue into the bend of my ear could make me damp a whole lot farther south. I explored the solid muscles of his back with my fingertips, then ran my nails over the quivering flesh at his side, before palming his extremely nice ass. It wasn’t enough. I needed to feel naked skin against skin more than I needed to breathe. â€Å"Can we take this to my room?† He lifted his head from a teasing lick across the lace-covered peak of my breast. Dawn threatened; just enough light filled the room so I could finally see his face. No more laughter, the need was as stark in his eyes as it was in my gut. Without a word, he got to his feet in a fluid, graceful motion and held out a hand for me. I could have made a smart comment. I could have ignored his hand. I wasn’t so far gone that I couldn’t stand up by myself. But the loss of his warmth, even in the heat of a summer night, made me shiver. I put my palm against his, let him bring me to my feet. Then hand in hand we entered my bedroom. It wasn’t much. A bed, a gun safe, a dresser. I slept there – nothing more. Until now. I had never brought a man into this room. The question of why not flitted through my head. I didn’t answer. 1 had better questions to occupy my mind right now. How quickly could I get him naked? How many times could he make me scream? Would he think I was weird if I asked him to tie me up and lick me all over? My first question was answered without my saying a word. He pulled his T-shirt over his head and shucked his jeans one second later, He didn’t wear underwear. Another mystery solved. I was tempted to turn on the light so I could see him, but then he could see me, and that didn’t tempt me at all. I was a big girl – everywhere. I swear that naked, I looked even bigger. I hovered just inside the doorway, suddenly unsure. He crossed the carpet in a sinuous movement that made me remember the loose-hipped gait of the big black wolf. The image disappeared when he reached out and unhooked the front clasp of my bra with a flick of his fingers. My breasts, suddenly free, popped loose with a near audible thunk. I had no time to be embarrassed. He lowered his head and rubbed his cheek against the fullness, breathed in as if he could catch my scent, then shoved my shirt and bra off my arms and latched onto a nipple with a scrape of his teeth and a push of his tongue. I’d read in some woman’s magazine that the larger the breasts, the less the arousal a woman gains from them. Considering how guys worshipped women’s chests and wanted to touch them in an ascending chart based on their size, I’d figured this was nature’s idea of a hysterical joke. But after reading said article, I’d been relieved. I’d always thought something was wrong with me. I could care less if a guy touched my breasts. Such pawing and panting below my neck had usually made me lose whatever interest I might have had. Now I understood I’d been with the wrong guys. Ca-dotte knew what to do. Gentle and sure, he aroused me with tiny suckles, openmouthed kisses, and murmured words of praise. By the time he bent and lifted me into his arms, my knees had begun to sag. â€Å"Hey!† The room spun as he strode to the bed. â€Å"I do not want to play kidnapped settler and Indian brave.† How rude, Jessie! My mother’s voice. Hell. I had to get rid of her. Cadotte’s laughter did it for me. â€Å"Maybe later.† He dropped me onto the mattress without warning and I bounced. At least that shut me up. My arms reached for him. He stepped back. Worried I had insulted him, I lifted myself onto my elbows. His gaze went from my face back to my breasts. â€Å"You know, they’re amazing.† He brought his eyes back to mine. â€Å"And so are you.† My chest had been my curse since the age of twelve. Once 1 had breasts, my friends who were boys could no longer seem to forget I wasn’t one, too. Since then guys had been trying to get their hands on my breasts. I had been trying to keep them off. No one had called my breasts amazing. The nicest thing a man had said about them was that they were â€Å"fucking big.† But in Cadotte’s dark, serene eyes I saw the truth. I was beautiful. At least until the sun came up. He flicked a finger at my pants. â€Å"Take ‘ em off.† Happy to. I kicked my boots across the room, lifted my hips, and slid the ugly tan trousers down my legs. My white cotton granny undies joined them. I might wear hooker bras, but I did not appreciate underwear that rode my crack like dental floss. I lay on the bed and he towered over me. â€Å"Such soft skin.† He trailed a finger up my knee. â€Å"Strong legs. Everything about you is beautiful.† â€Å"I-I like to swim.† Why I felt the need to talk, I have no idea. â€Å"I like it that you swim, too.† â€Å"I have a pond. On my land. The old Macray place.† â€Å"Shh.† He leaned over and kissed my belly. The urge to talk left completely. The bed dipped, but instead of covering me with his body and plunging away – which would have worked for me – he stretched his length next to mine, held his head with one hand, and trailed the other from my hip, across my belly, and back again. â€Å"Let me touch you, Jessie. I’ve been waiting forever.† I nearly pointed out that I’d only known him a few days, but I hesitated at branding myself a slut. Besides, I felt like I’d known him a long time. I seemed to have wanted him for a lifetime. Dangerous thoughts those, so I closed my mind against them and closed my eyes against all the things I saw flicker across his face as he touched me. How long we lay there, kissing, discovering, trailing fingertips across chests, hips, thighs, I’m not sure. When I opened my eyes, the dawn had spun gray shadows through my bedroom. I’d neglected to draw the shades again. I didn’t care. His body was even more spectacular in the daylight than it had been by the light of the moon. Just seeing him made me want him. He kissed me and got off the bed. The rustle of clothes, the crackle of paper, the snap of rubber – he’d come prepared. I was glad, since until this moment I hadn’t even thought of protection. Would I have let him do me on the floor without it? I guess I’d never know. When he rose over me and at last came inside, I kept my eyes open. I wanted to see his face; I wanted to watch my hands stroke his chest, my thumb tease a nipple. I wanted to know how he looked as I tightened and pulsed around him. His eyes didn’t cross, though mine did. He made no sound; I had to. He held me and stroked me both inside and out, until I was gasping, breathless, limp. I came back to myself and realized he was still big and hard inside me. Heat flooded my face. â€Å"What – ?† He swallowed my question with a kiss, didn’t stop tonguing me until I stopped trying to talk. Only then did he begin to move again. I’d always considered reports of multiple orgasms an urban legend. Guess I was wrong. He reached between us, stroked me where I was already sensitive until I was writhing and gasping, on the edge all over again. Then he lifted my hips and filled me with a firm, sure thrust. I felt him where I’d never felt anyone before. His hands taught me the rhythm. First fast, then slow, then something in between. Seeming to grow, to swell, he throbbed to the beat of my pulse. I gasped, tightened, came again as his teeth scraped the curve of my neck. He collapsed, his weight pressing me into the mattress. Trapped for a moment, I suddenly realized how big he was, how strong. Panic fluttered for an instant, until his palm cupped my hip and he rolled to the side. Our noses nearly brushed. In his eyes I saw uncertainty. Something I understood very well. My chest tightened. My belly fluttered. My unease was pushed aside by the urge to make that expression go away. So I touched his face and murmured, â€Å"Uncle.† How to cite Night Creature: Blue Moon Chapter 21, Essay examples

The concern laid out a viable extraction of information that focuses on several nations outside the Commonwealth Caribbean and their history of administration together with the leading factors of deviance in the civil services. Criterion used to assess the intricacies of Public Maladministration and Bureaucratic Corruption includes: injustice, unreasonable delay, abuse of discretion, negligence, arrogance, disregarding morality, employing deception and justifying criminality, nepotism, bribes, fraud, and waste and abuse in government. Public Administration is â€Å"centrally concerned with the organization of government policies and programmes as well as the behavior of officials (usually non-elected) formally responsible for their conduct†. The field is complex in nature due to the various sub-fields such as organizational theory, statistics, policy analysis, human resources, ethics, and budgeting. Woodrow Wilson – 1887, defined Public Administration as â€Å"the detailed and systematic execution of public law†. Therefore, it is the government’s responsibility to take rational action and manage human and capital resources to attain its goals. We will write a custom essay sample on Deviant Behaviour in the Civil Services or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Wilson is known to be the father of Public Administration. He wrote an article entitled â€Å"The Study of Administration†, and stated that â€Å"it is the object of administrative study to discover, first, what government can properly and successfully do, and, secondly, how it can do these proper things with the utmost possible efficiency and at the least possible cost either of money or of energy†. He also wrote in 1887 four concepts in which he believed: * â€Å"Separation of politics and administration * Comparative analysis of political and private organizations * Improving efficiency with business-like practices and attitudes toward daily operations * Improving the effectiveness of public service through management and by training civil servants, merit-based assessment† Deviance, when looked at sociologically, describes actions or behaviors that violate social norms, including formally-enacted rules. (eg crime. Norms are rules and expectations by which members of society are guided. When there is a failure to conform to these norms and they are defied, it can be considered to be deviant behaviour. This is quite common in administrative systems around the globe. The political term maladministration however, is linked to the actions of government bodies that cause injustice. Comparative Public Administration lecturer Maukesh Basdeo, stated that â€Å" Public Maladmini stration can be interpreted as a perversion of power, extortion, discrimination, intentional misperformance or neglect of a recognized duty. He goes on affirming that â€Å" public maladministration is a term derived from a purely post-French Revolution Western notion of public office based on the theory of the administrative state, the bureaucratization of government, the separation of political and bureaucratic career structures, the professionalization of public service, and the idea of public servants as trustees of the common good†. The government according to lecture notes is a public trust that must be used in the general interest and not for the benefit of particular sectional interests. Since public officials are â€Å"servants of the people and not vice versa†, it is a necessity that such officials be dedicated, obedient, hardworking, loyal, honest, patient, respectful and must have the ability to represent the people. They must also be highly productive and efficient and should be appointed based on merit not ascription. â€Å"The Western World has accepted this public service ideology and has, with varying degrees of success, exported it to the rest of the world.
